BERNARD MCHUGH, OF OTTAWA, CANADA.

DEVICE FOR CUTTING CARDS WITH BEVELED EDGES FOR PHOTOGRAPH-MOUNTS.

SPECIFICATION forming part of Letters Patent No. 524,726, dated August21, 1894. Application filed December 13, 1893. Serial No. 493,526. (Nomodel.) Patented in Canada October 25, 1893, No. 44.562.

. To all whom it may concern.-

Be it known that I, BERNARD MCHUGH, a SllbJGGil of the Queen of GreatBritain, residing at Ottawa,in the county of Carleton, in the Provinceof Ontario, Canada, have invented certain new and useful Improvements inDevices for Cutting Cards with Beveled Edges for Photograph-Mounts; andI do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part hereof.

This device is an improvement on a device for which I obtained aCanadian patent, No. 44,562, bearing date October 25, 1893.

The object of my invention is to produce a device whereby all the sidesand corners of a card may be cut simultaneously, cutting the card out ofa sheet of bristol or other board at one operation, instead of, as hasheretofore been the case, cutting the cards first with square edges,then piling several cards thus cut one above the other, the edges to betrimmed receding as they ascend, thus forming steps, then holding thepile thus formed in a press and trimming the edges with a scraper, thisoperation having to be repeated as many times as there are sides of thecard.

My device consists of a die of a truncated pyramidal shape having kniveson its sloping sides and angles, the knives being operatedsimultaneously by a block carried in a press and having a verticalmovement, the said block having sloping sides impinging on the upperedges of the knives.

1n the drawings,-Figure 1 is an elevation of my improved cutter, thepress being omitted. Fig. 2 is a top view of the die holding the cuttingknives (half only being shown). Fig. 3 is a vertical section on line 33, Fig. 2, showing the knives down. Fig. 4 is a Vertical section on line4 4, Fig. 2. Fig. 5 is a detail view of one of the side knives. Fig. 6is a partial section on line 6 6, Fig. 1, showirtg one of the angleknives. Fig. 7 is a detail view of one of the angle knives. Fig. 8 is asection showing the manner in which the corner knives are secured. Fig.9 is a detail view of an angle of the die.

A is a die of a truncated pyramidal shape. On each of its sloping sidesare formed one or "more cylindrical chambers a open at the top and alsoopen to the face of the slope. Two or more pins b are castin the dieprojecting at right angles to the sloping sides, and are threaded ontheir outer ends to receive the nuts 19 The angles O formed by thejunction of the sloping sides of the die are provided at their upperends with chambers 0, similar to though smaller than the chambers (1,pins b are secured in the die below the chambers, the lower portions ofthe angles 0 are formed with a dovetailed groove D deep at the base ofthe die and running shallower as it ascends as shown in Fig. 9.

The side knives E lie flat against the sloping sides, their upper edgesprojecting above the top of the die, the outer edges of the top of theknives being slightly rounded; each of these knives is provided with oneor more pins 6, these pins are received in apertures formed incylindrical bosses F, which are adapted to slide in the chambers a,spiral springs f being inserted in the bottom of the chambers, exertingan upward pressure on the pieces F, and so raise the knives; two or moreelongated slots G are formed in the knife E for the pins b, and plates'gare secured over the knives, the lock nuts b holding the said platesfirmly in position, leaving the knives free to slide. The cutting edgeof the knives E may be formed of a separate piece E and riveted to themain body, so as to be renewed when worn. The upper portions of theinner edges of the sides of the knives E are beveled to allow room forthe shanks of the corner knives.

H are corner knives, the cutting edges are rounded and they are soarranged that the edges are overlapped by the side knives, the loweredges of these knives slide and fit in the dovetailed grooves D, arather slender shank h (to facilitate placing the knife in the groove)connects the cutting portions with the head I, which is provided with aslot '5, through which the pins 19 pass and is secured with washer andlock nuts; a pin '5 is secured in the head which passes into an aperturein a sliding piece J, sliding in the chamber a, and provided with spiralsprings j similar to f; the tops of the heads of these knives have aV-shaped groove K, as shown in the detail.

In the center of the die A is formed an aperture L, open at the top andreaching nearly to the bottom, an aperture Z of smaller dimensionsconnecting with the larger aperture, is reamed out at the bottom; twosmaller apertures m are formedone on either side of the centralaperture.

N is a block in the shape of an inverted truncated pyramid, having onits under side pins M adapted to enter the apertures m. In the center ofthis block is an aperture 41. of a diameter large enough to receive thehead 19 of the pin P, this aperture is open at both ends, that is itpasses entirely through the block but at the under side is only largeenough to admit the body of the pin P, this pin passes down into theaperture L in the die A where it is secured by means of the screw R.

Spiral springs S may be inserted between the die A and block N. Theblock N is secured in any suitable manner to a press having a verticalmovement.

The operation of my device is as follows: The knives when in theirnormal positions, are held by the springs so that their cutting edgesare on a level with the lower edge of the die, the die being held to theblock N by the pin P, when the die touches the card the block continuesto descend, the sloping sides impinging on the upper edges of the sideknives, and the angles engaging the V-shaped grooves on the cornerknives, thus pressing the knives through the card, the head of the pinsliding up in the aperture n. The top outer edgeof the side knives beingrounded the pressure is on the inner side, directly over the cuttingedge. I

Having now fully described my invention, what I claim is- 1. A devicefor cutting cards with beveled edges, consisting of a die of a truncatedpyramidal shape, carrying slidingly on its sloping faces, springretracted knives, and on the angles formed by the junction of thesloping faces, spring retracted knives sliding in dovetailed grooves,the upper edges of all the said knives projecting above the upper faceof the said die, 'a block secured loosely to the said die and adapted tobe held in a press, the sloping edges of the said block impinging on andpressing down the said knives, when pressure is applied, substantiallyas set forth.

2. A device for cutting cards with beveled edges, consisting of a die ofa truncated pyramidal shape carrying slidingly, on its sloping facesspring retracted knives the upper edges of the said knives projectingabove the upper'face of the said die, a block shaped likean invertedtruncated pyramid, secured loosely by means of a pin to the said die,the head of the said pin being free to slide in the said block, thesloping edges of the said block impinging on and pressing down the saidknives when pressure is applied to the said block, substantially as setforth.

bosses, substantially as set forth.

at. In a device for cutting cards with beveled edges, the combinationwith the die A carrying spring retracted knives on its sloping sides andon the angles made by the junction of the said sloping sides; of theblock N having guide pins M and P adapted to enter apertures in the saiddie A, the head of the said pin P sliding in the aperture 7?, in thesaid block the said aperture being smaller at W BERNARD MoHUGl-I.
